As the global energy transition accelerates, solar energy is emerging as one of the most promising sources of renewable energy. From Europe and the Middle East to Southeast Asia, the Americas and Africa, a growing number of countries are building large ground-based photovoltaic (PV) plants to meet growing electricity demand and meet carbon reduction targets.
At the same time, the expanding scale of PV power plants also puts forward higher requirements for power safety. Surge protector is becoming an indispensable part of large-scale photovoltaic project as a key equipment to ensure stable operation of the system. In recent years, with the continuous growth of photovoltaic (PV) installed capacity, the global market demand for surge protectors has shown a significant upward trend.
As a professional manufacturer of surge protector, we are observing an increasing number of PV developers, EPC contractors and power operators incorporate SPD at the heart of their project design. This report examines the status and future trends of surge protectors in the global and Chinese markets. The major production areas, major consumer areas, and major manufacturers of surge protectors are analyzed in terms of production and consumption, respectively.
1.Global number of large-scale photovoltaic projects continues to Increase
In the past few years, the global PV industry has entered a rapid development phase.
A growing number of countries are building:
Megawatt-scale photovoltaic
Gigawatt-scale PV bases
Desert Photovoltaic Project
Agro-PV hybrid project
Aquaculture-PV hybrid projects
These projects typically have extensive coverage, long transmission lines and large quantities of equipment.
As the scale of the project grows, so does the risk of lightning strikes and shocks to the power system.
Therefore, surge protection has become an important component of the design of large-scale photovoltaic projects.
2. PV power plants are inherently at higher risk of lightning strike.
Compared with traditional indoor distribution system, PV power plants are exposed to outdoor environment for a long time.
For example:
PV module arrays
Combiner boxes
Inverter
Supercharged substations
Communications equipment
These are usually installed in open areas.
During a thunderstorm, even if there is no direct lightning strike, it can be triggered by lightning strikes.
The transient overvoltages generated by lightning can travel rapidly along the line, damaging critical equipment.
To mitigate these risks, project developers are increasingly emphasizing sustainable distribution (SPD) configuration solutions.
3. Increased inverter value lead to increased protection needs
The inverter is one of the core components of PV system. As technology improves, modern inverters integrate:
Power Control System
Intelligent monitoring systems
Communications module
Networking Control Module
The value of these devices is increasing.
If affected by the surge, it can lead to:
System shutdown
Loss of electricity generation
Increased maintenance costs
Decrease in project income
Therefore, it has become an industry consensus to equip inverters with high performance surge protectors.
4. The digitization of photovoltaic systems is increasing.
Modern large-scale photovoltaic plants are no longer just power generation facilities.
A growing number of projects are using:
SCADA monitoring systems
Remote operation and maintenance platforms
Meteorological monitoring equipment
Data acquisition systems
Intelligent communication networks
These electronic devices are highly sensitive to transient overvoltages.
Even a small surge event can lead to:
Data loss
Communication interruption
Failure to monitor
As a result, the need for surge protection has expanded from simply protecting power generation equipment to protecting the entire smart power system.
5. Growth of energy storage Systems Further Boosts SPD Market Growth
With the rapid growth of integrated photovoltaic energy storage projects, energy storage equipment is becoming an important part of the new energy field.
Energy storage systems typically include:
Battery set
PCS converters
Battery management systems
Energy management systems
These devices incorporate a large number of electronic components.
They are extremely sensitive to the impact of surges.
As a result, an increasing number of energy storage projects are being configured:
AC-side SPDs
DC-side SPDs
Signal SPDs
This has further boosted demand.
6. Keep raising industry standards.
With the maturation of the photovoltaic industry, the country has placed forward higher requirements for the safe operation of power plants.
A growing number of projects require:
Lightning risk assessment
Design of mine protection system
SPD configuration solution for the design phase.
For large commercial projects, surge protection has gradually changed from a "recommended configuration" to a "standard configuration."
The change is a direct push to expand the SPD market.
Conclusion:
With the rapid development of large-scale photovoltaic power station, the importance of surge protection is becoming more and more obvious. From protecting inverters and energy storage devices to ensuring the steady operation of communication systems and intelligent monitoring platforms, solid-state drives have become indispensable key equipment in modern photovoltaic projects. In the future, the the surge protector (SPD) market is expected to sustain long-term growth, providing a solid guarantee for the safe, efficient and sustainable development of the photovoltaic industry, as new energy installed capacity continues to grow and industry safety standards continue to improve.
Frequently Asked Questions
Why do large photovoltaic plants need surge protectors?
Because photovoltaic plants are exposed to the outdoors for long periods of time, they are vulnerable to lightning strikes and storm surges.
What type of SPD is typically installed in photovoltaic systems?
These include DC-side SPDs, AC-side SPDs and communication signal SPDs.
Can surge protectors protect inverters?
Yes. ' SPD can limit overvoltage to the inverter, reducing the risk of device damage.
Does energy storage system need SPD also?
Yes. ' Battery management and control equipment in energy storage systems also require surge protection.
Why is SPD market growing with the growth of the PV industry?
Because the larger the PV project, the higher the requirement for equipment safety and system reliability, thus driving the continuous growth of surge protection demand.
